A comprehensive encryption tool supporting multiple algorithms

Project description

加密工具 (CryptoTool)

这是一个基于Python的加密工具,提供了多种加密算法的实现,包括AES对称加密、RSA非对称加密以及混合加密方案。

功能特点

  • AES对称加密/解密
  • RSA非对称加密/解密
  • 混合加密方案(AES + RSA)
  • 文件加密/解密支持
  • 完整的错误处理和日志记录

安装

  1. 克隆项目到本地:
git clone https://github.com/yourusername/EncryptionTool.git
cd EncryptionTool
  1. 创建并激活虚拟环境:
python -m venv venv
source venv/bin/activate  # Linux/Mac
venv\Scripts\activate     # Windows
  1. 安装依赖:
pip install -r requirements.txt

使用方法

基本使用

from cryptool.core.app import CryptoApp

# 初始化加密工具
app = CryptoApp()

# 生成密钥
aes_key = app.generate_aes_key()
rsa_public_key, rsa_private_key = app.generate_rsa_keys()

# 加密/解密示例
text = "Hello, World!"
encrypted_text = app.encrypt(text, aes_key)
decrypted_text = app.decrypt(encrypted_text, aes_key)

文件加密

from cryptool.core.symmetric import AESHandler

# 加密文件
AESHandler.encrypt_file("input.txt", "encrypted.txt", aes_key)

# 解密文件
AESHandler.decrypt_file("encrypted.txt", "decrypted.txt", aes_key)

混合加密

from cryptool.core.hybrid import HybridHandler

# 生成混合加密参数
hybrid_params = app.generate_hybrid_params()

# 加密
encrypted_text = HybridHandler.encrypt(text, hybrid_params)

# 解密
decrypted_text = HybridHandler.decrypt(encrypted_text, hybrid_params)

配置

项目使用.env文件进行配置,主要配置项包括:

  • AES_KEY_LENGTH: AES密钥长度(默认32字节)
  • RSA_KEY_SIZE: RSA密钥大小(默认2048位)
  • LOG_LEVEL: 日志级别(默认INFO)
